CMP SuperFlo/SuperMax Pump Union Kit [1-1/2″ Slip] (21063-350-000)

Description

When repairing pool or spa equipment, small dimensional differences can create leaks, poor seating, or extra downtime; this union fitting gives technicians and homeowners a clearly identified option to compare against the existing part. It is used in plumbing service areas where matching the connection type and size is critical for leak control, easier equipment access, and a cleaner repair. Key identifying details from the listing include 1-1/2″ Slip. Because many CMP, Pentair, Water Ace, and related pool components can look similar at a glance, the part number 21063-350-000 should be used as the main confirmation point before ordering.

For best results, inspect the current part before removal, note how it is oriented in the assembly, and compare every visible size or style callout with this listing. If the product is being installed as part of a repair, also review the surrounding gaskets, collars, fittings, fasteners, or sealing surfaces so the replacement can seat properly and the repair is not compromised by an older adjacent component.
